COMBINED ROLLER AND BALL BEARING.

Specification of Letters Patent.

Patented Get. 31, 1916.

To 11/] who/r1 it may concern.

lle it known that we, Harrow ll. Wanna: and lu-tirrlr ll. RAILHUN, citizens of the lhiited States, residing at Seattle, in the county of King and State of Washington, have invented certain new and useful .lmprovcments in (.ombined Roller and llall Bearings, of which the following is a specification.

This invention relates to ball bearings for vehicle wheels, and its object is to provide means for locking the screw by which the bearings are adjusted to properly engage the balls; in ans for automatically working oil to the midway members of the hearing from theends where the oil is usually applied, and means for removably securing a series of balls in a spacing web.

To this end our invention consists in the construction and con'ibination of parts torming a combined roller and ball bearing herc inal'ter more fully described and particularly stated in the claim, reference being had to the accoimianying drawings in which- Figure I, is an end view of our combined roller and ball bearing. a portion being broken away, and the locking ring removed. Fig. II, shows a transverse section of the locking ring, and Fig! Ill, an inner face view of the same. Fig. IV. is an edgewisc view on a larger scale, of a portion of one of our hall- :arrying we s opened so that a ball may be removed or replaced, and Fig. Y, is a similar view oi the same parts with the web properly closed to hold a bull therein. Fig. VI, is a side or face view of a portion of the web carrying two balls. Fig. VIII, is a. side view of our ball b aring with pon tions broken away to expose to view certain parts hereinafter referred to.

Numeral 1 represents a bushing to be fitted into a, wheel at the hub, and serving as the outer wall of our hearings- On a sleeve -32, which is to be mounted on the wheel axle, is secured at 3, a. collar 4, which presses the, balls 5 against inner shoulders (S of the bushing 1 to receive the endwise thrust of the axle. Directlyover the screw thread 8, we cut a circular, concentric groove 7, one half in the sleeve 2 and the other half in the, collar 4, to receive a key ring 8, that carries the key pin 9. A series of half round holes 10, are made in the collar l at varying distances apart, and-another series of like holes 11 are made in the-sleeve 2 to register with the first named holes, one at a time, and form therewith a complete receptacle tor the key pin 5). At 12 such a receptacle is shown, and in Fig. VII, the key pin 9 is shown in service. The key ring 8 is bent outward along two sides to project normally beyond the face of the collar l, as shown in Figs. 11, and VII, for the double purpose of being kept in its groove 7 by the usual hub collar, and to enable the operator to'readily insert his linger nails under to remove it. We provide the end collars 13 of the cage that can ries the rollers H. with one or more scoops 15. at either their outer or inner edges, or both, shaped to scoop or wedge the oil they come in contact with, through the throat ll? toward the middle of the hearing. The spacing webs that -arry the balls,.comprise three collars, the still' middle collar 17 which if punched at equal intervals with somewhat circular notches to freely receive the. balls, and the two side collars 18 which are punched to register therewith. but with holes a little smaller than the halls, thus serving as side walls to retain the balls, vct permitting them to roll freely inthese recesses. Figs. V, and Y1, show how the outer prongs it of these side walls, at the recesses,- retain the balls from escaping radially, vet our plan is to secure these side walls resiliently against the middle wall 17 so they may spread apart, as in Fig. IV, to permit the balls to be inserted or removed between the prongs 19. A simple means of accomplishing this is to secure the collars 1T. 13, all together by a few rivets .20, placed tar as practi able from the prongs, and making the collars 17 of resilient material sutlieiently thin to spring apart at the outer edges, the little distance required.

The various parts-of this invention are -(l0SlgLl0ll with a iew to simplicity, easy construction 'and low cost.

We claim- In a combined roller and ball bearing, a web comprising three collars secured together side-by-si(.le, the central one being of stiff material and notched at intervals in its outer edge to freely receive the balls, and the side collars being notched to register with the center one, but with notches smaller than the diameter of the balls, and

the prongs at the sides of the notches hav in testimony whereof we 'affix our signaing nolimally less space between them than tmes in presence of two witnesses. the sai diameter whereby each ball may Y be individually cazged for free rotation, and ED F 5 means for securing the collars tegether for laterally resilient separatien ettheir-prongs, Witnesses: between which the bnlis may thereby be m- STEPHEN FRANKLIN PmRoE,
